PUC confirms asbestos pipes used for Sault drinking water

PUC confirms asbestos pipes used for Sault drinking water

A very small percentage of water mains carrying drinking water to residents of Sault Ste. Marie have asbestos in them, PUC has confirmed. Although there is some debate on the subject, Health Canada has concluded that there is no evidence ingesting the substance is harmful to your health. Recently, an episode of the CTV television program W5 reported that asbestos-cement pipes are used in many municipalities across the country to deliver drinking water to residents.

Victoria Gold, Yukon Water Board argue in court over higher security payment

Victoria Gold, Yukon Water Board argue in court over higher security payment

Water licences are required for most mining operations and typically come with a number of conditions, which may include a requirement to provide a security cash deposit so funds are available for clean-up and remediation efforts should anything go wrong. Every two years, mining companies are required to submit reclamation and closure plans, to ensure sufficient security. Buchan said Victoria Gold hasn't been in compliance with that process, pointing to a lack of information on adjustments to its heap leach pad involving certain recontouring work, and apparent snow removal obligations from that site.

Data from Mars rover Zhurong shows evidence of wind, and possibly water, erosion

Data from Mars rover Zhurong shows evidence of wind, and possibly water, erosion

A team of researchers affiliated with multiple institutions in China and one each from Canada and Germany, has found data from the Chinese Mars rover Zhurong over its first 60 sols, showing evidence of wind erosion and possibly impacts from water erosion, as well. In their paper published in the journal Nature Geoscience, they discuss what they have found thus far.

New research finds evidence of climate-driven changes to northern lakes

New research finds evidence of climate-driven changes to northern lakes

Across the Old Crow Flats in the northern Yukon, lakes are telling a story of climate-driven change. The traditional territory of the Vuntut Gwitchin First Nation (VGFN), the Old Crow Flats is recognized as a Ramsar Wetland of International Importance thanks to its more than 8,000 thermokarst lakes (up to 15 square kilometres) and ponds. Thermokarst lakes are formed by thawed permafrost and can be prone to drainage if they expand into low-lying areas. Kevin Turner, an Associate Professor in Brock’s Department of Geography and Tourism Studies and Fulbright Canada Research Chair in Arctic Studies at the University of Washington, has studied the area since 2007, and he says that warmer temperatures, longer summers and more rain are “priming this important landscape for continued climate-driven landscape change.”
